4. biological prevention and control: enter after the large water surface water body of pure fresh water at shrimp seedling, according to every mu of silver carp and each 50 tails of grass carp of putting into 0.5 jin/tail of specification, in order to eat up die of illness weak shrimp and balance algae picture, prevent transmission;
(3) Desalination phase feeding and management: during the desalination of shrimp seedling one-level, the special compound feed prawn slice of growing seedlings of throwing something and feeding, throw something and feed 3 every day, on average throws something and feeds once for every 8 hours, day every ten thousand tail 10g of feeding volume; Feeding time is 7:00,18:00,24:00, and evening, feeding volume accounted for 60% of day bait throwing in total amount; After must washing by rubbing with the hands with 350 object bolting silks while throwing something and feeding with prawn slice, throw something and feed, feeding method is evenly to splash in full pond; During secondary desalination, by No. 0 PP Pipe Compound of prawn, throw something and feed every day 4 times, Feeding time 7:00,12:00,19:00,24:00, day every ten thousand tail 90g of feeding volume; Also need in storage pond, holding pond, throw in 0.5g Vb, 0.1g Vc, tri-kinds of vitamins of 0.1g Ve by every cube of water body every three days, in case stress reaction;
(4) mature stage management is divided into: regulating and controlling water quality, feeding and management, routine testing, disease prevention and cure;
1. regulating and controlling water quality: select fine weather to change water, changed water once every 10-15 days, each quantity of exchanged water, at 10-15cm, changes water at every turn and all will sterilize, to reaching following water quality index: transparency 30-40cm, Ph value 7.8-9.0, ammonia nitrogen is below 0.1mg/L, and nitrite is below 0.03mg/L, and hydrogen sulphide is below 0.1mg/L, bottom dissolved oxygen is more than 3mg/L, and upper strata dissolved oxygen is more than 5mg/L; In the time that water quality index changes, regulate with corresponding substrate clarificant;
2. mature stage feeding and management: suitably shrimp seedling body length, more than 3cm, after namely secondary has been desalinated, adopts No. 1 PP Pipe Compound of prawn, and daily ration of feeding accounts for 10% of shrimp body weight; Shrimp-roe body length, more than 5cm, adopts No. 1 half PP Pipe Compound of prawn, and daily ration of feeding accounts for 8% of shrimp body weight; Shrimp-roe body length, in the time that 6cm is above, adopts No. 2 PP Pipe Compound of prawn, and daily ration of feeding accounts for 6% of shrimp body weight; Shrimp-roe body length, more than 8cm, adopts No. 2 half PP Pipe Compound of prawn, and daily ration of feeding accounts for 5% of shrimp body weight; Shrimp-roe body length, more than 10cm, adopts No. 3 PP Pipe Compound of prawn, and daily ration of feeding accounts for 2% of shrimp body weight; Set up multiple material platforms of looking in large water surface surrounding, within 1.5 hours, eat up material as standard take shrimp-roe; According to weather condition or epidemic disease situation, feed intake less or do not feed intake; Long-term rainy or cloudy, daily ration, feeding quantity reduces by half; Epidemic disease occur time, daily ration, feeding quantity be reduced to 1/3rd or stop material;
3. daily inspection, detection: patrol the pool at every morning, evening, midnight, observe change of water quality, by apparatus measures dissolved oxygen amount, Ph value, ammonia nitrogen, nitrite, hydrogen sulphide and six indexs of transparency, and make a record, expand shrimp-roe lethality in case further infect water body, cause immeasurable loss;
4. the use of aerator: 50 days prawn culturing early stages, rain, the cloudy day needs the long-time aerator of opening, conventional weather every day only at 3:00 AM to 7 unlatching aerators in morning; Prawn culturing stage, according to the reference that is determined as of dissolved oxygen amount, starts aerator every day and is no less than 15 hours, and aerator is placed according to clockwise direction, during cultivation every 15 days, by the rotation of aerator placing direction, fully stir water body, harmful substance can natural degradation by stirring;
